In model ST-2 significant improvements had been achieved in both accuracy and mechanical design. Replaceable tweezer tips had been introduced as well as a better insulation of the handles released in 2007.

In 2009 a rechargeable model of Smart Tweezers STIC (Smart Tweezers with Inductive Charger) was introduced in order to address a problem of housing damage due to multiple replacement of batteries. This model was more expensive but was widely accepted on assembly lines.
